Abstract: 933,355. Machine tool details. WARNER & SWASEY CO. Jan. 9, 1961 [March 4, 1960], No. 819/61. Class 83 (3). [Also in Group XXIV] In an hydraulically or pneumatically controlled cam mechanism, particularly for causing a tool-carrying slide 1 to be moved linearly by a motor-driven cam drum 5 towards or away from a workpiece 4 upon manual or automatic actuation of a valve 18, the drum 5 has a deep helical cam groove 23 interconnecting shallow arcuate grooves 21, 22 and is driven by a reversible motor 11. The helical groove has arcuate terminal portions of gradually decreasing depth merging with the shallow arcuate grooves to form a circumferential groove at each end of the drum 5. The cam drum is engaged by a roller 14 on a piston 12 in the slide 1, the piston being retained in an inner or outer position by a spring plunger 28. The piston slides in a cavity 13 coupled by a flexible hose 19 to the valve 18, which connects the cavity either to a pump 15 or to a reservoir 16. In the upper position shown, the roller 14 rides in the left-hand circumferential groove as the drum 5 rotates and the slide 1 remains stationary. When desired, the valve 18 is actuated in timed relation with the rotating drum to admit fluid to the cavity 13, whereby the roller 14 is projected downwards so that it follows the deep helical groove 23 and moves the slide to the right. Meanwhile, the valve 18 is actuated to connect cavity 13 to the reservoir 16 so that as the roller reaches and rides in the right-hand circumferential groove it is lifted to return the piston 12 to its inner position. The slide 1 is moved to the left by similar actuation of the valve 18 with the motor 11 reversed. The slide 1 is mounted on spaced ways 2 and may be retained in its forward and rear positions by spring detents. The motor 11 and valve 18 may be controlled by switches on the turret of a machine tool.

Title: Improvements in and relating to pulse receivers
IPC: H04L27/06
Filed: 1964-01-08
Abstract: 995,818. Telegraphy; transistor pulse circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 8, 1964 [Jan. 11, 1963], No. 890/64. Headings H3T and H4P. In a receiver for binary data modulated on a carrier, the received signals are demodulated and passed both to a bi-stable unit which generates mark and space pulses and to a threshold unit which, if the threshold is not exceeded, reverses the state of the bi-stable unit. It is stated that such an arrangement results in fewer bit errors in the interpretation of the received signals because a bit having a value below the threshold is more likely to be opposite to the previous bit than the same as it. As described, phase shift signals are received and are demodulated by mixing at 3 with a signal of carrier frequency derived from the received signal. The resultant signals are integrated at 8, 9, unit 11 discharging capacitor 9 at the end of each bit. The integrator output is amplified at 10 and fed on mark and space leads to bistable unit 16 to give mark and space output signals, and also via gate 21 to monostable unit 22 which has a threshold equal to the operating threshold of unit 16. When a bit does not exceed the threshold, gate 23 is enabled to allow a clock pulse to reverse the state of unit 16. The clock pulses, which also control unit 11, are derived from the received bits by way of filter 12, half-wave rectifier 13 and tuned filter 14.

Title: Tensile force control system
Inventor: YAMAZAKI CHIKAYASU
IPC: D01H13/32
Filed: 1983-01-06
Abstract: PURPOSE:To realize tensile force control under the most appropriate condition even for those of physical properties of different value in the longitudinal direction by controlling the receiving speed in a proportional integral circuit so that the tensile force comes to a constant value and adjusting the control gain of the circuit in proportion to the circuit output. CONSTITUTION:When a supply roller 2 is driven at a constant circumferential speed V1 after running a thread 1 of a package 10 through a measurement system, the thread 1 furnished with a definite tensile force is affected by thermal contraction by means of a heater 14 and generates stress. Tensile force T2 of the thread 1 is detected by means of a tensile force gauge 13 and sent to a controller 17, then compared with a set tensile force T1, subsequently a motor 7 is controlled to satisfy the formula T1=T2, and the circumferential speed of a receiving roller 6 is changed. An operation machine 16 obtains thermal contraction rate S of the thread 1 from the circumferential speed V1 and V2 of rollers 2 and 6 under the formula of T1=T2. At this time, an automatic gain adjustment circuit 27 determines a control gain G so as to put the loop gain of control system in proportion to DELTAV. This results in increase of control gain G correspondingly to contraction rate of the thread 1 in case the thread 1 contracts. Thus, there is no need of determining G by trial and error.
